Religion is not merely the opium of the masses, it's the cyanide.
The fact that a believer is happier than a skeptic is no more to the point than the fact that a drunken man is happier than a sober one. The happiness of credulity is a cheap and dangerous quality.
George Bernard Shaw
I'm an atheist, and that's it. I believe there's nothing we can know except that we should be kind to each other and do what we can for other people.
To assert that the earth revolves around the sun is as erroneous as to claim that Jesus was not born of a virgin.
Cardinal Robert Bellarmine
The sciences are not sectarian. People do not persecute each other on account of disagreements in mathematics. Families are not divided about botany and astronomy does not even tend to make a man hate his father and mother. It is what people do not know that they persecute each other about. Science will bring, not a sword, but peace.
Robert G. Ingersoll
I condemn false prophets, I condemn the effort to take away the power of rational decision, to drain people of their free will - and a hell of a lot of money in the bargain. Religions vary in their degree of idiocy, but I reject them all. For most people, religion is nothing more than a substitute for a malfunctioning brain.
Hast thou reason? I have. Why then dost not thou use it? For if this does its own work, what else dost thou wish?
“We are all atheists about most of the gods that humanity has ever believed in. Some of us just go one god further.”
No Gods - No Masters.
The invisible and the non-existent look very much alike.
